For the treatment of cracks in cement concrete pavement, many people will think of crack repair. Indeed, crack repair on cement concrete pavement is a common and effective method to solve cracks in cement concrete pavement. However, in the repair of cracks in cement concrete pavement, one of the notable problems is whether the repair of cracks in cement concrete pavement truly solves the problem of cracks in cement concrete pavement. Has it achieved the effect of treating both the symptoms and the root causes?
Cracks in cement concrete pavement, especially deep longitudinal cement pavement cracks, have an impact on the structural layer of cement concrete, destroying the integrity of the road structural layer and reducing the pavement strength. Such cracks have a very negative impact on the life and quality of cement concrete roads.
There are four main reasons for the cracks in cement concrete pavement. One is material quality, the other is construction quality, the third is subgrade condition, and the fourth is external factors. These causes may cause cracks in cement concrete pavement. Regardless of the cause of the cracks in the cement concrete pavement, the cracks in the cement concrete pavement will have an impact on the road traffic and quality. Therefore, cracks in cement concrete pavements need to be treated in a timely and effective manner.
How to deal with cracks on cement concrete pavement? What are the repair methods for pavement cracks? Huineng Luqiao believes that cracks in cement concrete pavements vary according to the severity of cracks, and the common crack treatment methods for cement concrete pavements mainly have surface layers. Both the repair method and the internal repair method, the surface repair method and the internal repair method need to use the cement pavement crack repairing material. The surface repair method is mainly applied to the surface micro cracks which have no influence on the road surface carrying capacity, and the surface repairing purpose. The main purpose is to close the surface cracks to achieve the purpose of anti-leakage; the internal repair method is to inject the cement pavement crack repair material into the crack, with the cement pavement crack repairing material coagulation and hardening, the cement pavement crack repair material and the crack interior Bonded together to restore the integrity and function of the structure, which is a commonly used cement concrete crack repair method.
The difficulty of crack treatment of cement concrete pavement varies according to the degree of crack. At the same time, the quality of crack repairing material used in cement pavement also directly affects the repair quality of cracks in cement concrete pavement. Hui Neng Road and Bridge suggestion: When selecting cement pavement crack repairing materials, it is necessary to select the cement pavement crack repairing material brand in all aspects, so that it can achieve twice the result with half the effort.
